Cisco Unified Communications Manager Express (CUCME or CME) is a software-based IP PBX that runs on Cisco routers. It provides basic call processing, routing, and IP telephony enablement functions. CME supports both SCCP and SIP protocols. Key features of CME include local directory service, call forwarding, call transfer, call park, pickup groups, phone templates, paging, single number reach for mobility, and hunt groups. Phones connect to CME via SCCP or SIP and are configured with directory numbers, buttons, and other settings. CME provides a cost-effective IP PBX solution for small-to-medium sized businesses.

Phones in Cisco Unified CME
Directory Number – EPHONE-DN
• A directory number, also known as an
ephone-dn for SCCP that represents the line
connecting a voice channel to a phone
• Each directory number has a unique dn-tag
• Directory numbers are assigned to line
buttons on phones during configuration
• One virtual voice port and one or more dial
peers are automatically created for each
directory number
• Number of simultaneous calls that you can
have
• Not all types of directory numbers can be
configured for all phones or for all
protocols

EPHONE – DN Single Line
• Single-Line
–Makes one call connection at a time using one phone
line button. A single-line directory number has one
telephone number associated with it.
–Should be used when phone buttons have a one-to-one
correspondence to the PSTN lines that come into a
Cisco Unified CME system.
–Should be used for lines that are dedicated to intercom,
paging, message-waiting indicator (MWI), loopback,
and music-on-hold (MOH) feed sources.
–Must have more than one single-line directory number
on a phone when used with multiple-line features like
call waiting, call transfer, and conferencing.
–Can be combined with dual-line directory numbers on
the same phone.

EPHONE – DN Dual
• Has one voice port with two channels.
• Supported on IP phones that are running SCCP; not
supported on IP phones that are running SIP.
• Can make two call connections at the same time using one
phone line button. A dual-line directory number has two
channels for separate call connections.
• Can have one number or two numbers (primary and
secondary) associated with it.
• Should be used for a directory number that needs to use
one line button for features like call waiting, call transfer,
or conferencing.
• Cannot be used for lines that are dedicated to intercom,
paging, message-waiting indicator (MWI), loopback, and
music-on-hold (MOH) feed sources.
• Can be combined with single-line directory numbers on
the same phone.

EPHONE – DN Octo Line
• An octo-line directory number supports up to eight active
calls both incoming and outgoing, on a single button of a
SCCP phone
• An octo-line directory number can split its channels
among other phones that share the directory number
• Octo-line directory number can handle multiple calls
because octo-line directory numbers do not require a
different ephone-dn for each active call
• After a phone answers an incoming call, the answering
phone is in the connected state. Other phones that share
the octo-line directory number are in the remote-in-use
state
• After a connected call on an octo-line directory number is
put on-hold, any phone that shares this directory number
can pick up the held call
• The Barge and Privacy features control whether other
phones are allowed to view call information or join calls on
the shared octo-line directory number.

Voice Network Directory
• Local Directory Service
• Name command under ephone-dn can be searchable from this local directory
• Names are used both for building the internal corporate phone directory (often called the local
directory) and for caller ID information
• By Default CME - organizes the local directory alphabetically by first name
• Also add manual entries to the directory by using the directory entry command
• You can add up to 100 manual entries to the local CME directory
CME_Voice(config-telephony)# directory ?

Configuring Call Forwarding
• Forward calls to a different destination
• To forward calls from the IP phone, just press the CFwdAll softkey button
• Forwarding calls from the command line gives you more options than does
forwarding callsfrom the IP phone
• Tandem hop in the call flow is the default call flow. When call is forwarded, Voice
traffic goes through the forwarding station thus quality can suffer
• H.450.3 standard represents a method that allows the CME router to redirect the call
directly to the final destination instead of acting as a tandem hop

• Call park system works by finding free ephone-dns where call will be held
temporarily. From the retrievable phone, just dial th ephone-dn number

Feature - Paging
• A paging number can be defined to relay audio pages to a group of designated phones
• When a caller dials the paging number (ephone-dn), each idle IP phone that has been
configured with the paging number automatically answers using its speakerphone mode
• Displays on the phones that answer the page show the caller ID that has been set using
the name command under the paging ephone-dn
• Audio paging provides a one-way voice path to the phones that have been designated to receive
paging

Single Number Reach in CME
• The Single Number Reach (SNR) feature allows users to answer incoming calls to their
extension on either their desktop IP phone or at a remote destination, such as a mobile phone
• Users can pick up active calls on the desktop phone or the remote phone without losing the
connection
• This enables callers to dial a single number to reach the phone user. Calls that are not answered
can be forwarded to voice mail
• Remote destinations may include the following devices:
–Mobile (cellular) phones
–Smart phones
–IP phones not belonging to the same Cisco Unified CME router as the desktop phone
–Home phone numbers in the PSTN. Supported PSTN interfaces include PRI, BRI, SIP,
and FXO
• Cisco Unified CME rings the desktop IP phone first. If the IP phone does not answer within
the configured amount of time
Mobile (cellular) phones.
